Activists documented bulldozers clearing land at Santa Elena Canyon in Big Bend National Park as part of the Trump administration's border wall expansion, funded by a $46.5 billion allocation. CBP initially denied the construction was underway despite video evidence, and DHS waived dozens of federal environmental and cultural protection laws to speed the project. Local business owners, river guides, and political leaders have opposed the plan, noting the area sees relatively few unlawful border crossings.
